408221 divided by 2 
Our goal is to divide 408221 by 2.

Going ahead to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 4 away from 4, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Going ahead to step 2:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 0 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 2

Moving on to step 3:
8 divided by 2 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 204.0
If we take 8 away from 8, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

Moving on to step 4:
If we divide 2 by 2, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 2041.0
If we take 2 away from 2, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Advancing to step 5:
The number 2 fits into 2 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 20411.0
Deduct 2 from 2 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Let's proceed to step 6:
1 divided by 2 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 204110.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 2 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 204110.5
If we subtract 10 from 10, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 204110.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 204110.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 204110.5 with a balance of 0.0.
